Percy solved the equation x2 + 7x + 12 = 12. His work is shown below. Is Percy correct? Explain. 1. (x + 3)(x + 4) = 12 2. x + 3 = 12 or x + 4 = 12

{x +4} {x+3} =0

Step-by-step explanation:

The equation is given as :

x² + 7x + 12 =0

Find multiples of 12 that can add to give +12 3 * 4

The equation can then be written as;

x² + 3x + 4x + 12 = 0  factorize

x{ x + 3 } + 4 { x +3 } = 0

{x+4 } {x + 3} = 0

Answer : {x +4} {x+3} =0

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
